.To alt whontit may conc-em:

Be it known that l., HOWARD W. Biricnn N, a citizen of the UnitedStates, and resident -oll llopedale, county of Wore-ester, State olMassachusetts, have invented an Improvement in (ut-ileasuring andStopping Means lor Looms, ol" which the yfollowing` description, inconnection with the accompanying drawing, is a specification, likeletters on the drawing` representing like parts.

rlhis invention has for its4 object the pro- `d ction of novel means formeasuring a predetermined length or.cut of cloth when woven on a loomandfor eilecting the stoppage of the loom automatically When the rut hasbeen Woven.

in cloth weaving the cut has a prede.- terinined length, differing withthe character ol the goods and with dil'lerent mills, but ordinarily:for aA given Weave-shed the length of the cut is fixed, and it isCustomary for the weaver to mark the "eut in some suitable manner.Sometimes this is done by weavingin so called hea-ders" at thecompletion ol each cut, as by Weaving two or more picks ol'V `fillingdiffering' in color or character from the Yllling in. the body of thecut, and it is higl ily desirable that all ,the cuts woven on a givenloom, or group of looms, shall-be of the same length. This uniformityiinthe length oi the out is secured by the present invention, and theconstruction ol" tl'iemecl'ianism such that an improper shortening ofthe cut by the Weaver is guarded against, while the automatic stoppageof the loom at the completion oi a cut enables one weaver to take chargeof a number oil looms and give general attention thereto, knowing thatno loom can Weave more. than the desired cut without being stoppedautomatically.

l have provided means for readily adjustf ing the measuring mechanism.by an authorized person, so that the desired length of cut will be wovenbei ore the loom is stopped, and the mechanism is so arranged that aftera eut has been started it is practically impossible for the weaver totamper with the apijiaratus witliout speedy detection, particularly asnf'eavers are forbidden to have in their possession any tool which wouldpermit ol' their ehz'mging any mechanism on the loom.

'lhe various novel features ol' my invention will be fully described inthe subjoined specilieati'on and paiti .eliuly pointed out in thefollowing claims.

Figure .l is a transverse see-tion of a Sullii cient portion of a loom,vxithone embodiment ol`v my present inve..ii-."1on applied thereto, thenearer loom-side being partly shown, the section in general being takenon the line ]-l, Fig. 2, looking toward the i eht; lf'g-2 is a l'rontelevation of the mechanism illustrated in Fig. 1 which is located at ornear lire right-hand side of' the loom, Fig. 3 is an enlarged detail intop plan vien' of a part of the instrmnentality for eil'ecting loomstoppage, taken below the. line 3 3, Fig; 2; "ign e. a partial sectionon the line iw-L Fig. f5; Fig'. 5 is a plan vieiY and section., taken onthe. line .5e-5 Fig. 2, of the tripping member governed by the measuringmoans;

Fig. 6 is a similar viev: ol" the tripping device but showing it in theact ol being opened or disengaged from the measuring means, in readinessto be moved manually 'to starting position preparatory to beginning aeut ol cloth Fig. 7 is a detail ol one part of the device for elleetingloom stoppage, to be referred to.

The breast-beam l, shipper 2, the clothroll shaft 3 on which the. clothis wound as taken up, the take-up roll fl, the cloth-guide 5 back oi'Athe take-up roll, the cloth-smvport (E, and supplementary support 7, seeFig. l., and tne mechanism for operating the takeup roll, may be of wellknown construction,

such for instance as shown inUnited StatesV Patent No. 789816, grantedto Nutting May 1e, i905.

In the present embodiment ol my invention l have operated thecloth-measuring mechanism by or through a convenient part oi thetalle-up, to wit, the take-up roll, because by so doing` a correctmeasurement of the actual cloth passinfjr over such roll is registeredbut it will be obvious that there are other moving parts of the loom.which could be used to aotuate 4the cloth-measuring mechanisn'i. T hatis, the motion of the lay could be utilized., for there is a definitemovement of the lay lor every pick put into the cloth. ,A

While the take-up mot-ion is most conveniei'it for the purpose, and Iprefer to use it any motion which gives a record of'or corresponds tothe number of picks put into the cloth, or gives the actual length ofthe cloth may ie utilized instead of the take-up lmo-r tion.

At one end of the take-up roll I attach a gear S which meshes With apinion 9 which in turn drives a pinion 10 fast on a horizontal shaft 11,see l 1g. 2, carrying at its outer end by an adjustable gear-plate 13,held in adjusted position en the cloth-roll stand 14 by bolt 15, so thatpinions of di'llerent diameter 4may be used.

',ihe cloth-roll stand le forms a part of the takeaip structure and isof Well known con* struction, except that herein 1 have shown itprovided with a sleeve-bearing 1GX for the. shaft 11, the bevel-gear 12on said shaft meshing with a. similar gear 16, lig. 2, fast on the upperend oi' a vertical shalt 17, screw'v threaded at 18 for the greater partof its length, as shown in liirs. 1 and 2, said shaft having an upperbearing in a shelf-like bracket 19 bolted to the loom-side AX, and alower step-bearing 20 being formed in a see ond bracket 21 bolted to theloom-side und to the cross-girtil?, lig. 2.

A `guide-rod 22 parallel to the threaded shaft 17 is held at its upperand lower ends in the brackets 1Q and 21, behind but a short distancefrom said shaft,the lower end of said guide-rod being held fast by aset-screw 23, big. 1.

lFrom the 'foregoing it will be manifest that the threaded shaft 17 .isrotated by or through the take-up roll, the transmitting; gearing beingso arranged and proportioned that for each complete revolution of thetakeup roll the shaft will be given a predetermined angular or rotativemovement, which is made operative to throw into action a loom-storminginstrinnentality when a predetermined number of revolutions of thetake-up roll have measured a certain number of yards off cloth, i. e. acut, as will be described. v

A tripping device mounted slidahly upon the guide-rod 22 and normallyoperatively engages the threaded part 18 of the shaft 17, to be movedupward by rotation thereof, said device beinO' herein shown comprisingtivo pivotally connected 'members 211, 25, the hub 24J( of the formerbeing bilnrc'atcd to embrace the hub 2. of the latter, both hubseinbracinfr the guide-rod 22, Figs. 5 and 6. The members oi thctrippingr device are thus adapted to be closed together, as in Fig. 5,toembrace the threaded partfl of the screw-shaft, by means of threadedseats 26, 27, or they can be swung` out to be disengaged from the shaft,as in Fig. 6. v

The free ends of the members are slotted, the slot in the member 211receiving the pivotally connected end of a threaded locking rod 28provided with a nut 29, said rod entering the slot 30 in the member 25,as in Fig. 5, se that by netting up the nut 29 the tripping device isioclred upon the screw shaft in operative engagement therewith, eee Fig.5. The member 24 is provided with' a lateral lug 31, and the member hastoc 2 extended therefrom near ils hub 25", lor I purposes to bedescribed a bevel-gear 12, the pinion 9 being carried lthen thcmeml'iers and 2S' are locked together ilicir opposed l'accs abut, sothat tighteningr ol the nut 2) cannot clamp the tripping;4 dcvicc. uponthe screw shalt.

when the tripping device is in operative engagement with thescre\vslml`t 17, as in Figs. 1, '2 and 5, the toe 32 extends ever :md isclose lo the projectini edge ol` thc eine plate 3G, so that even il thenut 2f.) is looscned the member 25 cannot be swung; around the guide-rod122 and disengaged from lhc scre\v'lhread 151, except when the loc l2 isopposite the notch 37. At such tiene the toe will suing' through thenotch and permits conniilcte opening el the trippingr device, it beingunderstood that when said dcvicc is eomplctcly open the toe .'12 willhave been moved still further to the lelt, viewing Vig. ll, beyond theedge of Idie gagemlale. Then upon the tripping; device. can he movedlfreely longitudinally oll thc guide-rod 22.

The position ol' the notch 37 dclcrmincs the starting point ol thetravel of the trip-V ing device, for when the toc. P12 is opposite thenotch the members 2i-l and ,Z of the tripping:r device can then beclosed and locked aroundthe scre\\'shul`t, and as the sopping point ofthe travel of said trippinpy device is always the same the movement ollthe g: ,geplate up or down will slierten or lengthen, respectively, thelength ol such travel. in auxiliary plaie 1l) is adjuslably secured lothe liar 35 above the upper end oi' thc gage plate 3G, to partly lill inthe space between the latter and the bracket 1i). Alcr thc trippingrdevicehns been locked :is dcscribcd und the upward travel bcggun cannot'nc unlocked so long; :is thc toe Ill? extends over the edge ol' thegege-plaie, hence hc travel of the triniing device must he, nly theymini mum, to the top oi 'aid plafi'c Shi, fis a mauter of lne-t whilethe weaver could unloclf.

Eril

lll() l1 fi d L that detection Would be made easy.

The auxiliary plate 40 is a safe-guard, as it makes it incumbent on aweaver to yvatcli the loom closely if there be any intention to r1 espipposite the space between the plates 36 an 40 the tripping device canbe un` locked. When runninr a number ol looms 4 46, to looselyreceivethe detcnt.

however,- a Weaver could not give this atten--4 tion toanyparticularloom and the chances ofA improper niilaipulation areininin'iized. When the tripping device arrives at the upper end of itstravel. the lug 31 acts'u ion a detent 41, lifting it from th'e'positions iown in Fig. 4 and out of engagement with a slioul- .der 42 on` alatch 43 releasing the latter.

This atch is reierably a squared portion ol a rod 44 slida le in abea-ring' 45 on the bracket 19,' the latch traveling in a seat 46 on thebracket and having an attached handle 47 slidable ina bearing 48, thebracket being eut outv at 49, see Fig. 3, adjacent the seat A spring j50 normally acts to move the' rod to the iight, Figs. 3 and 4, Wheneverthe detent 4l is .lifted to release the shoulder 42, suchspring-actuated movement etlocting the ac tuation of a loom stoppinginsti-uinentality, as will Abe explained.

The opening in the detent, through which the latch passes when released,is sul'liciently large for the purpose, as shown in Fig. 4, and when theweaver is about to start the loom after it has been stopped through the.action of the cut measuring means he pushes in the handle 47, againstthe spiing 50, the detent 41 dropping into operative position infront ofthe shoulder 42'on the latch, as

will be manifest, but before doing this the Weaver has unlocked Athetripping device and restored it to starting position.

In Figs. 1 and 2 the latch is supposed to be in the position shown inFigs. 3 and 4, and the tripping device has been 'mo ed, by rotation ot'the. screw-shaft 17, to a point abo .e the notch 37, indicating; thatthe wea ingfof a eut has begun, and the rise of the trippingdevice Willcontinue 'until the lng 31 lifts the detent and `releases'tlie latch 43.

ves

i 1The adjustment of t he gage-plate to the starting point for thetripping de ice is not made by the Wear er, but by the loom-lixer orOverseer, and there .is little likelihood of an atterri t being made bythe we'a' er to change vthe ac justnient, as tan'iperiingr with the.gage- Blate oi' the settingv serons 39 therefor' would )e (guicklynoticed by those in autl'iority.

I ereinl ha' 'e arranged the stoppage of the loom, at theconipletioiifot a cut, to be effected by or through the wmp-stop n:v)tion as an easv and lcon eiiient way of so doing', f

and in Fig. 1 a suiiicient portion ofa stopslprten the cut, so that whenthe toe 32 ar i measuring motion is shown substantially as illustratedin United States Pat-ent o. 672,824 igranted to ttim son May 7, 1901.

.A roc -shait F has an attached, double- .throw t'eelerf adapted toenp'ageand be arrested by a released detector d in either ot the twobanks or series shown, iibratory motionv beine' imparted to the feelerby or sl'ialt in. and thereby moves the 'knock-oilarm m2" to rcleaseithe`shipper 2, and stop the loom.

' ',lo make the. uarpstop-motion eil'ecti yc to stop the loom4 when acut? is completed l nimmt-loosely. on the rock-shaft' F anupturnediinecri ha' ingits tip bent at 52 into the path of one of thearmsf supporting thc feeler. Said iingfer has a depending extein sion 53connected by a link 54 with the la tch rod 44, see Fig. l.

Vlien the latch 43 is held by the detent, in Figs. 3 and 4, theextension 55 is positioned to throw tlietingcr loi-ward, with its tip 52outof the way ol' the arnix, but. when the latch released the spring .30ino es the rod 44 and link 54 to thr,l right, `-,ieninfr Fig. l, andsiiinning the extension 53 forward, shown in Fig. 7. This places thefinger tip 52 in posit ion to stop the teeler just as it' a detector inthe iront bank had arrested it, and thereupon the stoppinginstrnmentality of the looin caused to operate. l

Theivea er can tell uhcn the cut' measuring means has caused loomstoppage by notingr the position ol the enlarged end ol' the handle 47,for il a cut has been completed and the looni is stopped on account olsuch completion the handle will be projected to abnormal position.

It will 4be ob ions that the cut measuringn means, minprisinpr thescrew-shaft and the tripping device actuated thereby, is posi tivelyactuated by the take-up mechanism and under its control during theformation olv a cut.

The looiii cannot be started `unless the latch is in normal, lockedposition, as will he obvious troni the foregoingl description, and tholocking oi the latch properly positions the detent lor rel xase by thetrippinpr do ice when a cut. has been completed.
